Abstract

A melt-spinning apparatus comprises a cylindrical spinning pack housing 11 (Fig. 1) provided with a closure in the form of a piston 10 having an axial passageway 13 for the melt and a feed member 1 which is part of the main spinning apparatus and is provided with a melt inlet channel 2 coaxial with the passageway 13. Integral with the feed member 1 is a support member 3 for the housing 11. The member 3 is provided with an opening 4 for the filaments extruded through the orifices 8 in the spinneret plate 7 and with two guide rails 5. The underside of the feed member 1 has a sloping surface at 6. Between the bottom of the piston 10 and the feed side spinneret 7 contained in the housing 11 is positioned a metal annular spring diaphragm 9 the edge portion of the lower surface of which is soldered or welded to the rim of the inlet face of the spinneret 7 and the central position of the upper surface of which is welded or soldered to the raised portion of the undersurface of the piston 10 surrounding the outlet of the duct 13 in the piston. Before the housing 11 containing the spinning pack is inserted in the spinning head 3 the diaphragm is in an unflexed state. When the housing 11 is inserted into the space or recess between the parts 1 and 3 of the spinning head between the parallel guide rails 5, a sealing element 12 located at the top of the piston 10 slides along the sloping portion 6 of the undersurface of the member 1 until the feed duct 2 and piston bore 13 are in alignment. When the spinning pack is in this operative position, the diaphragm 9 is flexed downwards and acts as a spring urging the seal 12 against the portion of the underside of the feed member 1 surrounding the inlet duct 2. This portion of the underside is parallel to the upper surface of the element 12, the two surfaces function as the faces of a joint between the feed member and the piston or closure member of the spinning pack. In the modification shown in Fig. 2 the piston 10 is urged towards the seal 12 by an annular disc 15 of deformable resilient material which functions as a plate spring. The chamber between the inlet face of the spinneret plate 7 and the underside of the piston 10 is sealed by sealing rings or gaskets 16 and 17 of resilient material. The sealing effect of the two rings increases as the pressure of the melt rises.
